Historically for embedded platforms we leave calling
of_platform_bus_probe() to the bsp code so that weird boards can still
do weird stuff on the probe order. However, I'm all for making more
code common, so we can start with this and switch to per-board (or
per-SoC) calls only if it becomes necessary.
